Abstract
Systems and methodologies are described that facilitate supporting uplink soft handoff in a UMTS TDD wireless communication environment. A virtual active set (VAS) for each user device can be generated at the network side of the communication environment, and sectors listed in each VAS can be informed of their respective listings. Sectors in a user device's VAS can be provided with a scrambling code and resource assignments from a nominal sector serving the user device, which information can be employed, to attempt to receive and demodulate uplink signals from the user device at all base stations in the VAS thereof. Additionally, such resources can be employed to transmit power control and reverse activity commands to the user device on the downlink.
